AUTOMATIC GLASS-WASHING DEVICE.

Application led November 25, 1927, Serial No. 235,712, and in GermanyNovember 29, 1926.

Automatic glass washing devices are known in which the pressing of adrinking glass into position turns on a supply .of washing water thepressure whereof drives rotary interior 5 and outside brushes throughthe medium of a turbine wheel.

The present invention provides an improved device of this generalcharacter the preferred form of which differs from the known devicesprincipally in that the rotation of a turbine wheel is transmitted to ahorizontally mounted brush shaft through a countershaft, and in that thewashing water is forced into and over the vesselV to be f cleansed, bythe blades of the wheel and through a funnel and baiiie plate. The device is primarily intended for use in licensed retail premises tofacilitate and accelerate the cleaning of glasses and to save water.

A constructional form of the device is illustrated, by way of example,on the accompanying drawing the single figure of which represents alongitudinal section through the device.

injection vpipe 3 arranged at the top of a valve `casing 1 the lowerpart whereof is made rectangular so that the surface 4 may rest on theedge of a water tank or sink while the surface 5 bears against theinside wall of same. The rearend of the valve casing houses a spiralspring 7 and a conical valve 8, and a hollow shaft 9 is rotatablymounted in its forward portion. On this shaft is a large pinion 10 and awater wheel 11, the former being fixed to the shaft but the latter beingarranged to run idly thereon and being integrally connected with asmaller pinion 12. A countershaft 13 is disposed above both pinions 10,12and has idler pinions in mesh therewith as shown.

On the front portion of the hollow shaft 9 1 is a collar against which adisk 14 is screwed by a cap nut 15. The disc 14 is cut through (exceptfor a pair of spokes) so as to leave a substantially annular openingclose 4round the collar and provide a passage 16 open towards theturbine wheel. Said disc is also covered on the front side with felt andcarries, on its rim, one or more pairs of outside brushes. 17 whosebristles forward.

A pressure member 18, having a reduced portion facing the valve 8 andprovided with a groove 19, is displaceably mounted lnside The deviceincludes a feed pipe 2 and an.

project obliquely the hollow s baft 9, as is also a stem 20 carryinginterior brushes.

Between the turbine wheel 11 the blades 22 of which are 'open above,below and in the forward direction) and the disc 14 a funnel 21 is soarranged that the exhaust pressure water is compelled to iow into thepassage 1G whence it is guided into the interior of the glass 25 to becleaned. Moreover, above the moving parts is disposed a hood 23, insidethe top of which is mounted a battle plate 24 for the purpose ofdirecting some of the exhaustpressure water from the turbine wheel overthe outer surface of the glass 25. The stein 20 supporting the interiorbrushes is non-circular and the nut 15 -is provided with a correspondinghole so that relative longitudinal movement (but not relative rotation)is possible between the stem and the shaft 9. The stem is bored rightthrough to the end in order that the bottom of the drinking glass canalso be swilled with water.

l/Vhen the device is to be used, the feed pipe 2 is connected with awater pipe by means of a rubber tube. The drinking glass 25 is thenslipped over the interior brushes and pressed until its rim bearsagainst the felt covered disc 14 whereupon the stem 2O and interiorbrushes recede and push back the pressure member 18, thereby opening thevalve 8. Water now ows through the pipe 3, impinging against the blades22 of the turL bine wheel 11 and setting the latter in rotation, rotarymotion being thus imparted to the shaft 9, the stem 2O and the interiorand exterior brushes through the pinion 12, the pinions on thecountershaft 13 and the shaft pinion lO. Some of said water is deliveredfrom the turbine through the funnel 21 and passage 16 to the interior ofthe glass where it is brushed against the interior surface by therotating interior brushes; and some of said water is deflected by thebale 24 to the exterior surface of the glass'against which it is brushedby the rotating exterior brushes. At the same time water passes from themain by way of the slot 19 and the bore of the stem 20 to the interiorbottom of the glass. Consequently, the glass is quickly and efficientlyi cleaned.

When the glass 25 is withdrawn the valve 8 closes automatically to cutofi' the water supply and stop the operation of the device.

The pinion countershaft 18 reduces the speed to the desired value andintensifies the water is injected through the hollow stem into theinterior of the drinking glass at the bottom thereof.

A suiicient clearance is provided, in rear of the valve, to enable evenvery short glasses to be pressed into position until the rim makescontact with the felt covered disc. The long springing of the valve andthe long reach of the interior brushes serve the additional purpose thatthe valve is already open and the turbine running before the actual Work(especially of the outside brushes) begins.

Another important point is that the device does not requlre anyfastening, but can be simply placed on the rim of the Water sink Withwhich nearly every bar is fitted, and supported by two adjustable stays26 which bear against the sides of the sink or rest on `the bottom. t

Although one preferred form of'lmy glass washing device has been.described it will be apparent that modifications maybe made and Itherefore intend no limitations in the scope of my invention other thanthose imcleaned into position over the brush opens the water supplycasing, of countershaft gearing o eratively connecting the turbine wheeland rush, and means for guiding and 1n` jecting the water issuincr fromthe turbine wheel into and over the g ass.
